Abstract:

ICECAP is an auroral measurements program to acquire geophysical data required for the formulation and testing of models and predictive computer codes. The models and codes describe atmospheric ionization, excitation, and optical emissions in the Aurorally disturbed ionosphere. These codes are needed to assess and evaluate the operation of critical DoD radar and optical systems in nuclear disturbed environments. Auroral disturbances studied in ICECAP are similar to nuclear disturbances in that both are characterized by dramatic visual displays, enhanced infrared airglows, and enhanced plasma densities resulting from the interaction of energetic electronics with the atmospheric constituents. The general objectives ICECAP are to provide measurements of chemical emission processes occurring in the disturbed atmosphere to uncover unsuspected chemical or interactive processes leading to important infrared radiations to provide experimental data against which models and computer codes can be compared and evaluated and to provide data that can be used to update and improve theoretical models and predictive computer codes.
